Version 7.3 introduces new HTTP call profiling functionality for ASP.NET applications. HTTP requests now appear in the call tree as the parents of the .NET methods they originated, helping you relate your results to your actions in the application and letting you zero in on slow pages.

SQL Server Compact Edition is now supported for SQL call profiling: if your application sends queries to SQLCE, they'll automatically be profiled, whether the server is local or remote.

Version 7.3 also extends filtering to the method grid, adds a new link from Database Calls view back to the call tree, and fixes some bugs in the version 7.2 release. More details can be found in the release notes here.
